I have solved this for me, by increasing update interval to 2 days and setting the update time to be ~ 4.a.m. when I am usually home, asleep, in 3 meters from my wi-fi router. I did that with use of gconftool(link)
When I wake up and I see updates waiting icon I just pres update all. That does the trick for me.

I don't use data over cell network at all, can't afford it

Strange.
I never tweaked the update interval and I only got one
update shortly after I bought my N900 (to the latest V10.2010.19-1 ).

Did you look which version of the OS you have and which version
Nokia says you should have?
( http://conversations.nokia.com/2010/...e-release-1-2/ )
Do you interrupt download of the update somehow (e.g. going around in the flat with the N900)?
I hope my questions aren't too silly...

i think gerdich means updates for installed programs, not the firmware

Ok, sorry.
Then I would check which program does a constant update.
This would be a bug report candidate then.

ME2g, it's the Hildon Application Manager checking for updates, it's not any installed program, re-read the first few posts in this thread please

Thanks to everybody.

My hildon-application-manager has gone.
I'm a little bit sorry because I liked it (i'm loving the Hildon design!)

It's not necessary to have a flat with the n900.

I've got 250MByte per month for 5$. (Each MByte more costs 10 cents.)

I'm surfing for hours without pictures. Normally I don't use not even 50MBytes. At the end of the month I even can watch some youtubes or download applications.

Until now I had a WLAN connection (The students next to me allowed me to surf on their net. Now they have finished their studies and are gone.)

In the night the n900 did the actualizations by WLAN. But now everything is by 3G.

I use the n900 very often. All my prayers I do online and all informations of my bus and train are online. I use also the maps.

I'm very happy with my n900.

But this last days the update ate about 9MByte every morning by GPRS when I started the connection.

I hope that it will be different after tomorrow.

Could you please answer my question about how you could be sure it is HAM that does the updates? After i put it to do it once a week.. it has stopped looking for any updates.

Could it be your mail or something else?

There was a yellow icon with a "!" that announced new updates.

So it must be the HAM.
(It's only now that understand that word: HAM=hildon-application-manager.)



I would like to know why the iptable script doesn't work.
The author of the original script writes that the line:
$IPTABLES -A OUTPUT -o $INET_IFACE -p tcp --dport 80 -m state --state NEW -j ACCEPT

was necessary for sources.list to download.

If I use this line only for wlan0 and not for gprs0 it should block download for 3D shouldn't it?

can you just delete the access points or something like that?
You should still be able to connect to WIFI...

I did this in my wife's android which tries to go on the web every 2 minutes and she is on pay as you go.

in addition disable all repositories and disable all desktop widgets as these often can update from the web.
